I am not sure that can be done even if all agree. The rules were made by the one that had the right to do them. The boats were designed to perform according to those rules and in what regards wind they are:

"The existing rules in the protocol, the guiding document for this year’s competition, call for racing to take place in winds of up to 25 knots for the early rounds of the challenger series, known as the Louis Vuitton Cup. Those limits are to be increased to 28 knots for the final of the Vuitton Cup and then to 33 knots for the America’s Cup match in September,"

So if the boats cannot sail safely over 20k.... they have to make alterations on the boat and sail to make that possible and not change protocol.

Alterations cannot be directed. I mean they have a maximum sail size but they can make them small if they want. Of course that will give an advantage in light winds for the ones that will have a bigger sail...but for what I understood the conditions between 20K and 30K are pretty frequent in S Francisco bay and it will be of no use winning some races to have the boat capsized on another.

Probably there will be a way to modify the sail to allow it to be depowered, some movable parts that can open or close letting pass the wind or catching it.

Paulo,

as revised on May 22, 2013 (copy below) form part of these Regatta Director
recommendations.
Important additional notes to be read in conjunction with the recommendations
(i) These recommendations are made by the Regatta Director after the Review
Committee interviewed team personnel from all Competitors, and will be refined
as the further work identified above is completed.
(ii) The majority of the Regatta Director recommendations represent a consensus
of the Competitors.
(iii) These recommendations do not alter the responsibilities assumed and allocated
by the provisions of the Protocol or any other rules or document referred to in
the Protocol.
(v) Each Competitor is responsible for the method of implementing the
recommendations.
(vi) No recommendations can cover all possible risks or address risks that are
specific to Competitor specific designs.
(vii) No recommendations can ever eliminate risk of injury or death in what is an
inherently risky activity, and the participants must assume full responsibility for
all risks involved.
(viii) Each Competitor and crew member remain responsible for their own safety at
all times. Each Competitor and crew member must continue to make their own
decision to race, or to continue racing.

AC72 Safety Recommendations
(Issued November 21, 2012 & Revised May 22, 2013)
Safety Recommendations that should be implemented immediately
1. Personal Equipment
• ACRM recommends that each crew member wear:
a) Personal flotation meeting the requirements of RRSAC 40(a) worn as the
outermost garment. Note that crewmember names would need to appear
on the flotation device
b) A helmet meeting the requirements of RRSAC 40(b)
c) At least one knife that is accessible by either hand
d) A personal air supply of at least 45 liters
e) A harness with a tether or belay device
• ACRM recommends that there be a separate maximum weight allowance for
personal safety equipment.
2. Training
• ACRM recommends the following training:
a) Personal air supply training
b) Training which mimics escaping from under the net when the platform is
capsized
c) At least two crew members on board shall have completed First Aid
Training with specific course content focused on treating injuries more
likely to occur on board the AC72’s and how to deal with them while out on
the water
3. AC72 Equipment
• ACRM recommends the following equipment on the platform:
a) Righting lines permanently attached to each corner of the platform with all
righting lines accessible when the platform is at any orientation
b) Knives in the four corners of the trampoline accessible when the platform is
upright or capsized
c) Four spare personal air supplies of at least 80 Liters each on the trampoline
4. Rescue Boats and Equipment
• A rescue boat with at least 3500 kg towing capability
• ACRM recommends that the team rescue boat carry the equipment listed in
Attachment A as a minimum.
Safety Recommendations that need to be considered
1. Establishing common emergency drop off zones with the local authorities.
2. Establishing common safe recovery areas for capsized yachts.
3. 1K liters of flotation in the top of the wing to keep it afloat until a team rib can access it.
• The preference seems to be inflatable air bags
• ACRM believes it is best to allow the teams to determine how they prefer to
implement this.
• A separate minimum weight allowance would be added for this equipment.
